BY (A M? ATTORNEY United States Patent 3,161,372 ATTACHMENT (BF RIBBON AND THE HKE T9 SPUGL EAL Frank H. Kaufmann, Hnntingdon Valley, Pa, assignor to Steel Heddlc Manufacturing Company, Philadelphia, Pin, a corporation oi: Pennsylvania Filed May S, 1%3, Ser. No. 278,819 6 Claims. or. 242-476 This invention relates to the attachment of metallic ribbon to spools and the like. Such metallic ribbon has a variety of applications for conductors, for coaxial cable and other uses. The invention relates further to the attachment of other types of ribbon, filaments and wire, and textile fibrous elements to spools and the like.

in the winding of successive spools, particularly wit metallic ribbon no satisfactory mode of attachment has heretofore been available which can be utilized with continuous winding and with a minimum of interruption to the continuous operation.

It is desirable that the ribbon be fastened so that as exhaustion occurs a tension can be applied for operating a stop motion on the machine in which the ribbon is used.

It is the principal object of the present invention to provide a simple but effective attachment of ribbon and the like to a spool or bobbin.

It is a further object of the present invention to provide an attachment of ribbon and the like to a spool or bobbin in which the turns of the ribbon are utilized to assist in the attachment.

It is a further object of the present invention to provide an attachment of ribbon to a spool in which a small patch or strip of adhesive coated material is used with turns of the ribbon on the barrel to provide the attachment.

It is a further object of the present invention to provide improved methods of attachment of a metallic or other ribbon and the like to a spool or bobbin.

Other objects and advantageous features of the inven tion will be apparent from the description and claims.

The nature and characteristic features of the invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part thereof, in which:

FIGURE 1 is a view in elevation showing a plurality of spools in the process of winding;

FIG. 2 is a view in elevation showing the initial stages of the application of the attachment in accordance with the invention;

FIG. 3 is a view in elevation at a later stage in the application of the attachment;

FIG. 4 is a view in elevation showing the filled spool subsequent to the attachment; and

FIG. 5 is a view in elevation showing the manner of holding by the attachment.

It should, of course, be understood that the description and drawings are illustrative merely and that various modifications and changes can be made in the structure and methods disclosed Without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several views.

Referring now more particularly to the drawings, a

- rotatable winding mandrel is shown with a plurality The vat and may be of copper, aluminum, steel, or any other desired metal or metal alloy, with or without an 3,151,312 Patented Dec. 15, 1964 exterior coating and is of a width equal to a plurality of times its thickness, but other metallic or textile strands, filaments or wire may be employed.

If it be assumed that a spool H, such as the spool at vthe right of FIG. 1 has been filled and a transfer made over the flange 14; of the next spool 11 to the left, or that upon starting or transfer the ribbon 15 is brought over a flange 1d of this spool, the mandrel It) is rotated and ribbon 15 fed by a traverse mechanism or the like (not shown) to provide a plurality of spaced helical turns 15a on the barrel 13.

The rotation of the mandrel ill and feed of the ribbon 15 is continued to reversely wind the ribbon on the barrel 13, as shown in FIG. 2, with a plurality of spaced turns 15!) superposed in crossing relation on the turns 15a.

The ribbon 15 is then preferably severed providing a starting terminal end portion as at 15c at the flanges l4 and the free end of the starting terminal end portion 15d back wound with one or more helical turns 15e superposed on the previously wound turns 15a and 15b and the free end 15d secured by the application of a small strip 16 of adhesive coated material. For this purpose pressure sensitive adhesive coated tape may be employed.

The ribbon 15 is helically wound onto the tube, preferably with successive turns 15 in closely spaced or edge meeting relation as in FIG. 4 until the spool is filled to the desired extent.

The transfer of the ribbon over the flange 14 of the filled spool to the next successive spool ill can then be effected and the operations previously described are repeated.

When the filled spool is utilized, and the metallic rib-.

bon 15 is drawn therefrom as the end of the ribbon 15 is approached the ribbon 15 catches and is held by a bight 15g. This places the ribbon in tension for actuation of the stop motion mechanism which stops the machine and prevents further demand for ribbon 15.

It will thus be seen that an effective bight 15g is provided which prevents the free end 15d of the ribbon or the like from being drawn to the place of use with resultant break in the continuity thereof. There is pro vided a tension in the ribbon or the like for stop motion mechanism operation.

I claim:

1. An attachment of ribbon or the like to the barrel of a spool comprising ribbon or the like with a plurality of spaced helical turns on the barrel extending from a starting terminal end portion in one axial direction, a. continuous plurality of helical turns on the barrel in the opposite axial direction, the starting terminal end portion being wound in superposed relation to a plurality of the first mentioned turns to provide a bight around a portion of one turn of the last mentioned turns, a member securing said portion to the barrel, and a plurality of helical turns superposed thereon.

2. An attachment of ribbon or the like as defined in claim 1 in which said member is an adhesive coated strip.

3. An attachment of ribbon or the like as defined in claim 1 in which the direction of winding of the terminal end is of opposite hand from that of the preceding turns.

4. An attachment of ribbon or the like to the barrel of a spool comprising ribbon or the like wound in spaced turns successively in a plurality of axial directions along the barrel and having a bight portion on the barrel formed by a reverse turn, the ribbon extending through the bight in engagement therewith.

5. The method of attaching ribbon or the like to the barrel of a spool which comprises applying a plurality of spaced turns onto the barrel in one axial direction extending from a starting terminal end portion, continuing r 3 7 the winding and applying a plurality of spaced turns in the 7 References Cited in the file of this patent reverse axial dlreenon and 1n superposed relation to the p UNITED STATES PATENTS first turns, winding the termlnal end portlon onto the I barrel in superposed relation to at least a portion of the 908,209 crompton 29, 1908 turns extending in the reverse axial direction to provide 1592432 af July 2 1926 a bight through which the ribbon extends, and securing 2,335,038 Bndges 23, 1943 2,800,290 Hess July 2 3, 1957 the terminal end portion onto the barrel.
